Guidance on Grouping of Chemicals, Second Edition
This guidance document is part of the OECD effort to provide guidance for assessing
the hazards of chemical substances while gaining efficiencies and improving animal
welfare. The approach described in this guidance document is to consider closely related
chemicals as a group, or category, rather than as individual chemicals. While the
first edition was published in 2007, This edition has been augmented with experience
and examples encountered in the OECD Cooperative
Chemicals Assessment Programme, formerly the HPV Chemicals Programme since 2007, the
second edition also intends to introduce new or revised guidance on: elaborating the
analogue and category approach, quantitative and qualitative read-across, justifying
read-across, using bioprofiling results for grouping chemicals, and specific types
of category approaches (e.g. chemicals of variable composition, and metals).
